(N0 model.)

To all whom, it Hung concern:

Be it known that I, GEORGE F. Nnwnnn, of \Vest Newton, county ofMiddlesex, State of Massachusetts, have invented an Improvement inMachines for Covering Webbing for Boot-Straps, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to machines for covering webbing for bootstraps.

Heretofore machines of the class mentioned have been constructed inwhich a continuous ribbon of webbing was covered with a tube or coveringof paper, and the webbing so covered was then automatically cut intopieces 'suitable for straps of the desired length,

whereupon the paper tube or covering was perforated or slittedtransversely at points between those'portions or ends of the boot-strapwhich are usually fastened or stitched to the boot or shoe, and the loopor central exposed portion and the tubing covering such ends orfirst-mentioned portions were stripped from the webbing, thus leavingthe loop or exposed portion only covered and protected by the papercovering. In this my invention the webbing is automatically fed from oneend of the machine into a suitable tube arranged above a table, and thencut into pieces suitable for straps of the desired length. About thesame time a ribbon or sheet of paper from the paper roll, which is of awidth equal to the length of that portion of the length of webbing whichit is desired to cover-namely, the central or what forms the loop orexposed portion of the strap when attached to a bootis fed from one sideof the machine across the table and below the tube containing the pieceof webbing, when a paste-roll applies paste to one edge or side of thepaper as the latter is out into a proper length. The strip of webbingand the piece of paper are seized between a forwarding roll and belt andprojected through a folder having a flaring mouth, which causes thepaper to be folded or lapped over onto the central portion of webbing,and is then passed under a pressure roll and pasted. The webbing, withits central portion covered by the paper tube, is then fed over a pairof rolls and forced or doubled between them by means of a plunger, whichthereby folds the length of webbing in its center, when the said foldedwebbing or finished boot-strap is delivered from the machine and may bedropped into a suitable receptacle. By this means there is no waste ofpaper after the webbing has been covered, nor is there any ragged ortorn edges of the paper covering; but, on the contrary, the bootstrap isdelivered from the machine in perfect condition with only that portionthereof which forms the loop or exposed portion after the strap isattached to a boot covered and protected by a paper tube.

The nature of the invention is fully disclosed in the followingdescription, and is particularly pointed out in the claims.

Fig. 13 is a detail side elevation thereof; Fig. 14., anelevation of the knife-bladeslo more clearly show the form of the upperor movable blade; and Fig. 15, a detail of the shaft carry-l ingthepaper roll and the mechanism for automatically regulating the speed ofsaid rollshaft.

The frame-work A of the machine, of suitable size, shape, andconstruction to support the operating mechanism, rests upon a bed, B,supported on legs B. The main or driven shaft a, bearing in the upperpart of the frame A, has a pulley, a, fiy-wheel a and a spur-gear, awhich last conveys motion through the gear-wheel a, secured to shaft aheld in bearings on the frame, to the gear.

(1 attached to one end of the webbing-feed shaft (5*, which in turn isheld in bearings fastened to the frame A. A partial roll, 2, ar-

ranged above the table Land having a circumferentiallyrgrooved face,co-operates with the full-faced circumterentially-grooved feed-roll 3.suitably held in bearings immediately below said table 1,to feedto thecutters or knives the webbing, which is drawn from a suitable reel, 4,attached to brackets placed in the frame-work in such position that thesaid webhing may be passed between suitable guiderolls, w, thence ontothe table 1, and into the tube 5, which, with the table 1, is providedwith slots 6, to permit the grooved faces of the rolls 2 and 3 to'intermittently grasp and feed the webbing past the knives b and into thewebbing-tube 7, (see Figs. 6 and 8,) when said knives operate to cut thewebbing into suitable lengths, as it is thus intermittently fed intosaid tube.

The knives 1) (see Figs. 3 and 5) consist of a lower stationary knifefixed to a cross-piece of the frame A and an upperor movable knifeattached to a kniieplate, b, which is connected by the pivoted links I)to said frame, so as to operate in connection with the stationary knifelike parallel rulers, whereby in cutting the webbing the movable knifehas a sliding or lateral as well as a downward movement. Further, themovable knife is slightly wider at 'one end than at the other, orsomewhat of a ta-- pering form in the direction of its length, asclearly shown in Fig. 14, whereby it has a shearing movement whenoperated to sever the webhing. An intermittent motion is imparted to themovable knife by means of an arm, b provided with a pin, 12*, whichengages with the can fgroove in the face ofthe wheel b fixed on shaft a,as indicated in Figs. 1 and 5. An angular blade, 0, is secured to thearm b and is provided with a hooked portion, 1), to part- 1y encirclethe shaft a, to give steadiness to said arm as it is reciprocated by thecam-wheel 1) The webbing-feed shaft a, having the spurpinion a at oneend. is provided at its opposite end with an eccentric, 0, (see Fig. 2,)and on the band 0, which encircles the same, is formed an arm, 0',having a ball-and-socket joint, to receive a finger, c, which is madefast to the paperfeed shaft (Land is capable of movement in the ball ofthe ball-and-socket joint, and, further, is provided with aspring-actuated pawl, 0 enngaging the ratchet-wheel d, (see i shaft,having its bearing in the frame A beneath the table 8, the lowerfeed-rolls, d receiving motion from the upper feed-rolls by frictionalcontact. One end of the web of paper on the roll 9 is placed between therolls d",-

(1", whereby the paper is drawn from the roll 9 and fed to and beyondthe paper out-ting knives e and onto the main table 1 below thewebbing-tube 7, which is disposed slightly above said table, to permitthe passage of thepaper under it, the said tube containing a piece ofwebbing, as hereinbefore stated, which is ofa proper length to form aboot-strap. The

paper from the roll 9, ofa width equal to the length of the centralportion ofthe piece of webbing to be covered, is fed onto the main table1 until its end is at the side of said table opposite the knives 6, whenthe said knives, being ofthe same form, construction, and operation asthe knives I), cut the paper into strips of a length equal to the widthof the table 1, they thus being sufficient to envelop the webbing, andstill have overlapping edges, which are pasted together in the mannertobe presently described.

The knives e are secured to the frame A at ,a

point between the said two tables, and an intermittent motion isimparted to the upper or movable knife by the arm 6, attached thereto,

(see Figs. 12 and 13,) and having the finger e, engaging the cam-grooveof the wheel e, se-' cured to the webbing-feed shaft a. Just before orabout simultaneously with the cutting of the strip of paper by theknives e, a film of paste is applied to the end of said strip farthestremoved from the said knives by means of a paste-1 011,). having araised portion or rib, f, along its face and parallel with the axisthereof, the said roll having a combined rotary and reciprocating motionto press the rib f against the face of agummed roll, 7, working in apaste-box,f, the rollf supplying the rib with a film or coating ofpaste, which in turn is transferred to the strip of paper by contacttherewith on the return motion of the pasteroll f. Asupplemental roll, farranged above and operating in connection with the 'gummed roll f, maybe provided, if desired. The paste-rollf has movable spring-actuatedbearings in the upper ends of two rock-standards, f whose lower ends arepivoted on a shaft,f"',se-

cured in the frame, (see Figs. 9 and 10,) and to the standard nearestthe delivery end of the machine (see Fig. 10) is firmly attached one endof a short arnrf whose opposite end works in the peripheral cam-grooveof the IIO . oted on the tappet and engaging the teeth of wheel fast onthe shaft Thus; by the retation of shaft g a reciprocating; motion isgiven to the paste rollf through the rockstandards. At the same timearotatory move ment is imparted to said rollf by means of thegear-pinion g fixed on one end of the pasteroll, which engages the teethof the rack-bar 9 attached to table 1, (see Figs. 1 and 5,) whereby therib f is alternately brought in contact with the gum med roll and thestrip of paper on the table 1. The gummed rollf is provided with a fixedpinion, g, and a loose tappet, (see Fig. 11,) the latter engaging theextended bearing g of the paste-rollf, so that as said roll is moved tothe gummed roll the extended bearing slides upon the curved uppersurface of the tappet to depress the same, which thereby induces thepawl g pivthe ratchet to partially rotate thegummed roll, and as thepaste-rollf is moved from the gum med rollfthe spring 9 (see-Fig.10)forces the tappet upward to hold it against the extended bearing 9and to keep the pawl in engagement with the teeth of the ratchetg. Apiece of webbing of the proper length having been fed into the web-tube7' and severed by the knives b, and a strip of paper to form thecovering for the central portion of the piece of webbing having been fedinto the table 1 below the tube 7 and severed and gummed, as described,both paper and webbing are then carried into the folder it by portionsof the mutilated roll 71, fixed on shaft It, and entering a slot, 7*, inthe tongue 7 of the tube, and by the belt It, (see Fig. 3,)running overpulleys if If, secured, respectively, to shaft g. heretofore mentioned,and shaft h. The shaft h receives its motion from gear a", which engagesgear h". The belt it enters a slot in the table 1, to thus come incontact with the paperlying thereon, and thence passes on the upper sideof said table through the folder is, (see Fig. 8,) and then throughanother slot near the delivery end of the machine and onto the pulley h,as shown. Motion is communicated to shaft 9' and h from gear if, fixedon shaft h, through the idle-gear t, pinion i" (see Fig. 4) on oneend'of shaft i", and the pinion i, (see Fig. 3,) secured to said shaft iin the body of the machine, and gears #15 respectively made fast to saidshafts g and h, as shown in dotted lines, Fig. 3. Immediately abovepulley h is a partial-faced roll, in, fixed to shaft 10, and receivingmotion from the idle-gear 6 through gear 11, made fast to said shaft 10.As in the operation of the machine the mutilated roll it enters theslotted tongue 7, the piece of webbing and the strip of paper having afilm of paste along one side are caught between the full-faced portionof the mutilated roll and the belt h", which then feed said webbing andpaper, the former on top of the latter, into the folder it, whichbein'gof a tapering form, with flaring mouth and upturned inwardlyprojecting or folding sides, with one of said sides higher than theother, (see Fig. 7,) the strip of prevent the edges of the piece ofwebbing from curling. by reason of the paper covering being folded oversaid webbing too closely. As the paper is being folded about the centralportion of the webbing, which is to form the loop of the bootstrap whenapplied to the boot, the

forward or uncovered end of said webbing will be passed by the belt. hto the rotating press-roll m, which, pressing the webbing against thebelt it, will draw said webbing between the parts until that portionhaving the paper covering is reached, when the pressure on the coveredwebbing between the roll at and belt h will cause the overlapping endsof said paper covering to be fully pasted together. From the partialroll at the piece of webbing is fed along the table 1 to and over tworolls, a a, (see Fig. 8.) rotating toward each other, until the middleofthe covered portion is above the space or junction of the two rolls,when the folding-blade of the plunger 0,Which has averticalreciprocating motion, forces the covered webbing or completed boot-strapbetween said rolls, and it is then delivered from the machine. The rolla is provided with disks a on either side thereof, to retain the webbingon said roll between the disks, as will be readily understood. Motion isconveyed to the rollsn a from gear on shaft it, through the idlepinion ato the gear on shaft of roll a, which in turn meshes with a similar gearon. shaft of roll a, as clear- 1y illustrated in Figs. 1 and 3. Toattain the reciprocating motion of the plunger 0. its end opposite tothat carrying th e, foldingblade is pivoted in the bracket 0, Fig. 9,and is intermediately connected with the band of the cocentric 0,fastened on the shaft 10, as shown in Figs. 1 and 9. Motion is given tothe shaft 9, secured in bearings 19 beneath the bed B, aid carrying thepaper roll 9 by means of a belt, 19*, running over a pulley, g, on thewebbing-feed shaft a, (see Figs. 1 and 5,) and over a pulley, g, on theshaft Q, arranged in bearings secured to the leg I) of the bed 13 atright angles to shaft 1), said shaft Q. carrying a friction-wl'leel, r,adapted to slide on the feather r, and being in frictional contact withthe disk o on the contiguous end of the shaft 29, to rotate the saidshaft, as stated, and as shown in Fig. 15. As theroll of paper isdecreased in bulk in the operation of the ma chine, the speed of theshaft 19, carrying the paper roll 9, is correspondingly andautomatically increased, to provide a regular feed of the paper to themachine by means of a presswheel, 8, journaled in the lower end of theIIO arm 8, which is secured at its other end to the shaft 8, mounted inbearings 3 fixed to the under side of the bed B, the said shaft 8'having alever, t, engaged by a spring, a, fastened to the bed B, whichspring-actuated lever ttends to turn its shaft 5 to keep the Wheel 8constantly pressed against the periphery of the roll of paper, wherebyas the diameter of said roll becomes lessened the shaft 8 is partiallyrotated in its bearings by the spring-actuated lever, to cause one ofthe fingers o, secured to said shafts and engaging the friction-wheel r,to move it on the feathered shaft Q toward the center of the disk 1' andthus increase thespeed ofthe roll-shaft 10.. A coiled spring, 10,encircles the shaft p between its disk r and the contiguous bearing 10,to insure the requisite frictional contact between the said disk and thewheel 0', as will be readily understood. The importance of thisprovision for an even regular feed of the paper will be seen when it isremembered that the paper is intermittently fed to the table bythefeed-rolls d, and it is therefore essential that the paper should bedelivered to the rolls as fast as required; otherwise it would tear ifthe weight of the roll of paper or the slower delivery-speed of the pa ter-roll shaft had to be contended with.
